Recent extreme weather has caused Norwich city water to take on a slight unpleasant odor and change in taste, but officials say it’s safe to drink.

Norwich Public Utilities reports on its website that a period of prolonged heat on the tail end of a spate of heavy rains has changed the reservoir environment, affecting the water’s taste and smell. Chilling the water before consuming it may reduce of eliminate the odor.

“Please be assured that this naturally occurring condition is not harmful,” the NPU update says, citing the utility’s routine sampling of the water supply.

NPU says it is taking “the necessary corrective measures” and expects the issue to be resolved soon. NPU can be reached by calling (860) 887-2555 or emailing communitymatters@npumail.com.
